Safety functions

Hold mode

Display:

The Hold mode is a safety state during configuration and cali-bration. The loop current is frozen (Last) or set to a fixed value(Fix).If the calibration or configuration mode is exited, theTransmitter remains in the Hold mode for safety reasons. Thisprevents undesirable reactions of the connected peripheralsdue to incorrect configuration or calibration. The measuredvalue and “HOLD” are displayed alternately. The Transmitteronly returns to measuring mode after enter is pressed and 20 seconds have passed.

Configuration mode is also exited automatically 20 minutes(timeout) after the last keystroke. The Transmitter returns tomeasuring mode.Timeout is not active during calibration.

Behaviour of output signal:

Last: The loop current is frozen at its last value.Recommended during short configuration procedures.The process should not change decisively during con-figuration. Changes are not noticed with this setting!

Fix: The loop current is set to a value that is noticeablydifferent from the process value in order to signal thecontrol system that the Transmitter is being worked at.

For configuration see Pg 51.

31

Outputs

Current output / Loop currentThe loop current is controlled by the process variable selectedin the configuration.The current beginning and end can be set to represent anydesired value. To check connected peripherals (e.g. limitswitches, controllers), the loop current can be manually speci-fied (see Pg. 41).

HART communicationThe Transmitter Cond 7100 e/2(X)H can be remote-controlledvia HART communication. It can be configured using a hand-held terminal or from the control room. Measured values, mes-sages and device identification can be downloaded at any time.This allows easy integration also in fully automatic processcycles.

A list of the HART commands can be found in the “Transmitter Cond 7100 e/2(X)H Transmitter-Specific CommandSpecification”: www.mtpro.com/transmitters.

AlarmThe alarm delay is configurable.Error messages can also be signaled by a 22 mA loop current(see Configuration, Pg 55).

The alarm LED on the front panel can be configured as follows:HOLD off: Alarm: LED flashing HOLD on: Alarm: LED on. HOLD: LED flashing.

Concentration measurementFor the solutions listed above, the Transmitter can determine the substanceconcentration from the measured conductivity and temperature values in% by wt. The measurement error is made up of the sum of measurementserrors during conductivity and temperature measurement and the accuracyof the concentration curves stored in the Transmitter, see Pg 84 et seq. We recommend to calibrate the Transmitter together with the sensor, pre-ferrably in the same conductivity range as measured later. For exact temper-ature measurement, you should perform a temperature probe adjustment.For measuring processes with rapid temperature changes, a separate tem-perature probe with fast response should be used.

Information on calibrationCalibration adapts the Transmitter to the conductivity sensor. Calibration can be performed by:• Input of cell constant (e.g. for ultrapure-water sensors)• Determining the cell constant with a known

calibration solution• Sampling (product calibration)• Temperature probe adjustment

Note:• All calibration procedures must be performed by trained

personnel. • During the calibration procedure the temperature must be

kept constant.• Incorrectly set parameters may go unnoticed, but change the

measuring properties.

Particularly with stray-field sensors the cell constant can strong-ly vary when the sensor is mounted in restricted space. In thatcase, the cell constant should be determined with the sensormounted using a calibration solution or by a reference meas-urement at the product.

Notes : (also see Pg 59)


For product calibration the measured variable is used as configured:Conductivity (µS/cm, mS/cm, S/m), resistivity (MΩ·cm). During productcalibration the sensor remains in the process. The measurement is onlyinterrupted briefly.Calibration is without TC correction.

Procedure: During sampling the currently measured value is stored inthe Transmitter. The Transmitter immediately returns to measuringmode. The calibration mode indicator flashes and reminds you thatcalibration has not been terminated. The sample is measured in the lab or directly on the site using aportable meter. To ensure an exact calibration, the sample temperatureshould correspond to the measured process temperature. The samplevalue is then entered in the Transmitter. The new cell constant is calcu-lated from these two values. If the sample is invalid, you can take overthe value stored during sampling. In that case the old calibration val-ues are stored. Afterwards, you can start a new product calibration.

SensocheckContinuously monitors the sensor and its wiring. Sensocheck can be switched off. Critical values make theSensoface “sad” and the corresponding icon flashes:

The Sensocheck message is also output as error messageErr 33. The red LED is lighted, the output current is set to22 mA (when configured correspondingly). Sensocheck canbe switched off during configuration (then Sensoface is alsodisabled). Exception: After a calibration a Smiley is alwaysdisplayed for confirmation.

Sensoface(Sensocheck must have been activated during configuration.)

The little smiley in the display (Sensoface) provides informationabout the sensor condition (defects, maintenance required,cable capacitance too high). It alerts to significant sensor polarization or excessive cablecapacitance e.g. caused by an unsuitable cable or a cable thatis too long. The permitted calibration ranges and the condi-tions for a friendly, neutral, or sad Sensoface are summarized inthe following chart. Additional icons refer to the error cause.

Note:The worsening of a Sensoface criterion leads to the devaluationof the Sensoface indicator (Smiley becomes “sad”). To reset the Sensoface indicator, the defect must be remediedand the Transmitter be calibrated.

Glossary

Conductivity Conductivity χ [S/cm] = G [S] · c [1/cm]

Conductivitysensor

Either 2- or 4-electrode sensors can be con-nected. The cell constant of the sensor inuse must be entered or be determined usinga calibration solution taking account of thetemperature. A special device variant (Transmitter CondInd 7100 e/2(X)H) is provided for electrode-less sensors.

Conductance G [S] = 1 / R [Ω]Conductance

Temperaturecoefficient

With temperature compensation activated,the measured value is calculated to the valueat the reference temperature (25 °C) usingthe temperature coefficient.

Temperaturecompensation

Calculates the measured conductivity valuefor a reference temperature.
